1 Description The is a 3-terminal adjustable shunt regulator with guaranteed thermal stability over a full operation range. It features sharp turn-on characteristics, low temperature coefficient and low output impedance, which makes it ideal substitute for Zener diode in applications such as switching power supply, charger and other adjustable regulators. has the same electrical specifications as the industry standard 431 except that it features a low minimum cathode current for regulation. The typical value of 50µA makes the parts ideal for very low power dissipation applications. The output voltage of can be set to any value between V REF (2.5V) and the corresponding maximum cathode voltage (36V). The is offered in two grade initial voltage tolerance at +25 C, 0.5% and 1%. This IC is available in 3 packages: TO-92 (ammo packing), SOT-23 and SOT-89. LOW CATHODE CUREENT ADJUSTABLE PRECISION SHUNT REGULATOR Features Low Minimum Cathode Current for Regulation: 50µA (Typ.), 100µA (Max.) Programmable Precise Output Voltage from 2.5V to 36V High Stability Under Capacitive Load Low Deviation of Reference Voltage Over Full Temperature Range: 11mV Typical (-40 C to +125 C) Sink Current Capacity from 100µA to 100mA Low Dynamic Impedance: 0.1Ω (Typ.) Wide Operating Temperature Range: -40 C to +125 C Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free. Green Device (Note 3) Applications Charger Voltage Adapter Switching Power Supply Graphic Card Precision Voltage Reference Notes: 1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant. 2. See for more information about s definitions of Halogen- and Antimony-free, "Green" and Lead-free. 3. Halogen- and Antimony-free "Green products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and <1000ppm antimony compounds.
